Can The Nhs Do Tests For Food Intolerance?

i know the nhs can do test for allergies,like skin/blood tests etc but can they test for food intolerances? i bought a first step test from yorkplus and they said i was highly positive and what ever im intolerent to i need to stop for at least 3 months.The next step is £249.99 and i carnt afford it :(
i have spoke to my doctor and she said to wait 2 more weeks till i see a neurologist as he will do bloods anyway,instead of having 2 blood tests gonig here there and everywere,she said they can check for allergies but nothing bout intolerance
